For this indicator, the performance of California counties ranges from a low of 53% to a high of 91%.

Individual county performances on the above indicator are grouped below into six categories, based on population density (i.e., "Rural" or "Urban") and per capita income of families with children (i.e., "High Income," "Middle Income," or "Low Income"). In doing so, the Scorecard encourages its users to look beyond the data from their own county, to the data of counties with similar physical and economic environments, as a way to discover new, effective strategies being used by other communities with comparable constraints and resources.
